Package: libzstd1 Version: 1.5.7+dfsg-3+b1 Severity: normal Tags: patch upstream Forwarded: https://github.com/facebook/zstd/issues/4628 Control: affects -1 src:cmake
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Dear maintainer, libzstd causes the CMake test suite to fail on i386 and armhf. CMake upstream has traced the problem to a large 2G compression buffer which fails to allocate on 32-bit systems. The problem can be worked around by either disabling ZSTD_MULTITHREAD (which is probably not desirable), or by adjusting the buffer size as done in the following patch: diff --git a/lib/compress/zstdmt_compress.h b/lib/compress/zstdmt_compress.h index 91b489b9..acd4d124 100644 - --- a/lib/compress/zstdmt_compress.h +++ b/lib/compress/zstdmt_compress.h @@ -32,8 +32,8 @@ #ifndef ZSTDMT_JOBSIZE_MIN /* a different value can be selected at compile time */ # define ZSTDMT_JOBSIZE_MIN (512 KB) #endif - -#define ZSTDMT_JOBLOG_MAX (MEM_32bits() ? 29 : 30) - -#define ZSTDMT_JOBSIZE_MAX (MEM_32bits() ?
